As the market floods (I've never seen so many Fender custom shop basses for sale on the used market) with used basses it's definitely a buyers world. Just curous about the craftmanship and quality of the Fender Custom Shop line: Are there periods just like the other lines that are better than others? Are they really "custom basses" or is just another Fender marketing guise? Is there any difference to the quality between models: ie, P vs. J? There are quite a few I've got my eye on, but if it's just hype - I'm not going to waste my mojo.
